Joule Electra preamps and amps. What is your impression?

I see. Is retubing with NOS expensive? 

Thaluza, thank you very much. So..great sound but possible problems with noise. No problems with preamps. Could be "labour of love" indeed. Since the tubes last a very long time this should not be much of a concern, I just don't want to pay $200/$300 per tube when I need at least ten or twelve of them.
In any case, within the next two/three years I would like to be in a process of replacing my SS phono and the integrated amp with all tube pieces or at least getting tube phono and preamp and maybe SS amp. Phono may actually come first.

Thaluza, 
Thank you. The owner's retirement may or may not be a complication for me, I would have to think about it.
Yeah, I like the idea of all tube electronics, SS amp would most likely be a temporary solution, though I would do my best to avoid even that.

Thaluza,

Appreciate your guidance. Yes, I would consider built-in phono too, but I strongly prefer separate phono stage. It also allows me to record onto tape directly not through tape-out.

This is an interesting situation. It appears that preamps would be an excellent choice, as for phono amd amps, there may be too many compatibility issues and noise problems.Hmm..

Sbank, yes I saw it too. Atma-Sphere are expensive. Did I hear right that OTL amps require a very careful match with speakers ? In what sense? I read that some use them with big Sound Labs, Classic Audio's modern vintage speakers are apparently excellent match too. But that's big unusual speakers. How about common dynamic speakers ?

My speakers have a nomibal impedance of 8 ohm and I have no idea of the curve. Audiokinesis makes interesting speakers, I think, never heard them, though. Audio Note, Harbeth, Spendor are not for me, I guess.
Powerful SET sounds good to me.

 Thank you, Atmasphere. It is Michael Green Audio Revolution 80i free resonance speakers. 
You know, though it is difficult to assess while listening to youtube, that set-up - Classic Audio speakers, your amps, Purist Audio cables and some turntable sounded really good, I think. I would improve the source, though, but it's a guess. It's the video posted on Purist Audio website.

Rich, you are welcome.

Ralph, thank you. When I switched from 60 watt/ch amp to 120 watt/ch amp, both ss integrated, there was a big improvement at all volume levels, though the current amp is of higher quality too. But I can definitely hear that the increased power is beneficial. So 60 watt/ch of tube power should be just right, and 100 watts wouldn't hurt.
